99566213 divided by 254 
The aim is to understand the frequency of 254 in 99566213.

On to step 1:
The number 254 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 254

On to step 2:
When dividing 99 by 254, we get 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 254

On to step 3:
The number 254 fits into 995 3 times, leaving a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 762 from 995 to get 233.
Append the next digit (6) from the dividend to 233 and continue with: 2336 / 254

Going ahead to step 4:
The number 254 fits into 2336 9 times, leaving a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 2286 away from 2336, we end up with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 254

Step 5:
254 can be fit into 506 1 times, resulting in a remainder of 252.
The next digit of our result is 1. 
Result so far: 391.0
Deduct 254 from 506 and we're left with 252.
Append the next digit (2) from the dividend to 252 and continue with: 2522 / 254

Moving on to step 6:
When dividing 2522 by 254, we get 9 with a remainder of 236.
Put 9 as the next digit of the answer. 
Result so far: 3919.0
Subtracting 2286 from 2522 leaves us with 236.
Grab the next digit (1) from the dividend, add it to 236, then carry on: 2361 / 254

Moving on to step 7:
The number 254 fits into 2361 9 times, leaving a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 39199.0
Deduct 2286 from 2361 and we're left with 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 254

Step 8:
254 can be fit into 753 2 times, resulting in a remainder of 245.
The next digit of our result is 2. 
Result so far: 391992.0
If we subtract 508 from 753, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 9:
When dividing 2450 by 254, we get 9 with a remainder of 164.
Put 9 as the next digit of the answer. 
Result so far: 391992.9
Deduct 2286 from 2450 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 10:
1640 divided by 254 is 6 with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 391992.96
If we subtract 1524 from 1640, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
If we divide 1160 by 254, we get 4 and a remainder of 144.
Record the quotient 4 as the next digit in the result. 
Result so far: 391992.964
Subtracting 1016 from 1160 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
254 can be fit into 1440 5 times, resulting in a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 391992.9645
Subtracting 1270 from 1440 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 13:
1700 divided by 254 is 6 with a remainder of 176.
Record the quotient 6 as the next digit in the result. 
Result so far: 391992.96456
Subtracting 1524 from 1700 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 14:
254 can be fit into 1760 6 times, resulting in a remainder of 236.
The next digit of our result is 6. 
Result so far: 391992.964566
If we subtract 1524 from 1760, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The quotient of the division is 391992.964566, and the remainder is 2.36e-05.
